Description of the core columns that persist throughout OES bottomfish sampling datasets. While the data have not changed from previous InPort records (see Nodes 11630, 11652), this is part of an effort to standardize and streamline all life history program databases for past and future cruises. This data set includes separate catch logs from each LHP Bottomfishing cruise both within and outside of the Main Hawaiian Islands, as well as a master file with all records.

Fishing operations that focus on targeting bottomfish (mostly juvenile opakapaka) that are independent of a larger research vessel, i.e. the Oscar Elton Sette.

Contains information collected such as: lengths, weights, sex, quantity, species, etc. from various bottomfish and pelagic species during frequent visits to the United Fishing Agency Fish Auction in Honolulu, Hawaii.

Catch, effort, location (latitude, longitude), relative abundance indices, and associated biological data from groundfish multi-species bottom trawl surveys in Queen Charlotte Sound (QCS), Hecate Strait (HS), West Coast Vancouver Island (WCVI), West Coast Haida Gwaii (WCHG) and the Strait of Georgia (SOG), British Columbia. Introduction This is a set of long-term and coordinated surveys that together cover the continental shelf and upper slope of most of the British Columbia coast. The objectives of these surveys are to provide fishery-independent abundance indices of all demersal fish species available to bottom trawling and to collect biological samples of selected species. The surveys follow a random depth-stratified design and the sampling units are 2 km by 2 km blocks. The synoptic bottom trawl surveys are conducted by Fisheries and Oceans Canada (DFO) in collaboration with the Canadian Groundfish Research and Conservation Society (CGRCS), a non-profit society composed of participants in the British Columbia commercial groundfish trawl fishery. The Queen Charlotte Sound and West Coast Haida Gwaii surveys are conducted under collaborative agreements, with the CGRCS providing chartered commercial fishing vessels and field technicians, while DFO provides in-kind contributions for running the surveys including personnel and equipment. The Hecate Strait, West Coast Vancouver Island, and Strait of Georgia surveys are conducted by DFO and have typically taken place on the Canadian Coast Guard research vessel W.E. Ricker. In years when the W.E. Ricker has not been available, the Hecate Strait and West Coast Vancouver Island surveys have taken place on chartered industry vessels.

This layer is intended to represent the geographic extent of NOAA Fisheries’ U.S. West Coast Groundfish Bottom Trawl Survey. The U.S. West Coast Groundfish Bottom Trawl Survey started in 1998 and is led by NMFS Northwest Fisheries Science Center. This survey provides long-term time-series data for the management of West Coast groundfishes as well as coastwide environmental sampling for monitoring change within the California Current Ecosystem. The bottom trawl survey covers West Coast waters (55-1280 meters [30-700 fathoms]) twice annually using a trawl net and a random sampling design, stratified by depth and latitude. The survey collects fishery-independent data on abundance, distribution, and biology of most species included in the west coast groundfish management plan. Weight and measurements are collected from vertebrates and invertebrates alongside various biological samples. Samples collected include otoliths and other structures for aging, finclips for genetics, gonads for reproductive analysis, and stomach contents and tissue samples for diet/stable isotope analysis. Oceanographic sensors are affixed to the trawl net, collecting data such as temperature, salinity, and dissolved oxygen for each trawl at depth.

Accurate and precise stock assessments are predicated on accurate and precise estimates of life history parameters, abundance, and catch across the range of the stock. In its continued efforts to improve the data used in stock assessments, the NOAA Pacific islands Fisheries Science Center (PIFSC) implemented a Bottomfish Fishery-Independent Survey in Hawaii (BFISH) in 2016. The BFISH survey utilizes two gear types, Cooperative Research hook-and-line fishing operations (CRF) and the Modular Optical Underwater Survey System (MOUSS). Survey sampling is conducted annually, typically in the fall, surrounding the Main Hawaiian Islands (MHI), in accordance with a stratified-random sampling design. Under this design, the waters surrounding the MHI are gridded at 500 meter resolution. Each grid is given attributes of depth, slope, and seafloor hardness. Depth categories are Shallow (75-200 meters), Medium (200-300 meters) and Deep (300-400 meters). Slope categories are Low slope (0-10 degrees) and High (10-90 degrees). Seafloor categories are Hardbottom and Softbottom. Annual survey data are processed to produce relative and absolute abundance and biomass estimates for the Stock Assessment for the Main Hawaiian Islands Deep 7 Bottomfish Complex. This dataset contains information from BotCam deployments conducted during the 2011-2015 methods comparison study, which led to the operation BFISH survey.

Catch, effort, location (latitude, longitude), relative abundance indices, and associated biological data from groundfish multi-species bottom trawl surveys in West Coast Haida Gwaii. Introduction The West Coast Haida Gwaii (WCHG) synoptic bottom trawl survey was first conducted annually from 2006 to 2008 and has since been repeated every second year on even numbered years. The survey was not impacted by the COVID-19 pandemic. This survey is one of a set of long-term and coordinated surveys that together cover the continental shelf and upper slope of most of the British Columbia coast. The other surveys are the Queen Charlotte Sound (QCS) survey, the Hecate Strait (HS) survey, the West Coast Vancouver Island (WCVI) survey, and the Strait of Georgia (SOG) survey. The objectives of these surveys are to provide fishery independent abundance indices of all demersal fish species available to bottom trawling and to collect biological samples of selected species. The survey follows a random depth-stratified design and the sampling units are 2 km by 2 km blocks. The synoptic bottom trawl surveys are conducted by Fisheries and Oceans Canada (DFO) in collaboration with the Canadian Groundfish Research and Conservation Society (CGRCS), a non-profit society composed of participants in the British Columbia commercial groundfish trawl fishery. The Queen Charlotte Sound and West Coast Haida Gwaii surveys are conducted under collaborative agreements, with the CGRCS providing chartered commercial fishing vessels and field technicians, while DFO provides in-kind contributions for running the surveys including personnel and equipment. The Hecate Strait, West Coast Vancouver Island, and Strait of Georgia surveys are conducted by DFO and have typically taken place on a Canadian Coast Guard research vessel. Until 2016 this vessel was the CCGS W.E. Ricker. From 2021 onwards, this vessel was the CCGS Sir John Franklin. In years when a coast guard vessel has not been available, the Hecate Strait, West Coast Vancouver Island, and Strait of Georgia surveys have taken place on chartered industry vessels. Data from these surveys are also presented in the groundfish data synopsis report (Anderson et al. 2019). Effort This table contains information about the survey trips and fishing events (trawl tows/sets) that are part of this survey series. Trip-level information includes the year the survey took place, a unique trip identifier, the vessel that conducted the survey, and the trip start and end dates (the dates the vessel was away from the dock conducting the survey). Set-level information includes the date, time, location, and depth that fishing took place, as well as information that can be used to calculate fishing effort (duration) and swept area. All successful fishing events are included, regardless of what was caught. Catch This table contains the catch information from successful fishing events. Catches are identified to species or to the lowest taxonomic level possible. Most catches are weighed, but some are too small (“trace” amounts) or too large (e.g. very large Big Skate). The unique trip identifier and set number are included so that catches can be related to the fishing event information (including capture location). Biology This table contains the available biological data for catches which were sampled. Data may include any or all of length, sex, weight, age. Different length types are measured depending on the species. Age structures are collected when possible for species where validated aging methods exist and are archived until required for an assessment; therefore, all existing structures have not been aged at this time. The unique trip identifier and set number are included so that samples can be related to the fishing event and catch information. Biomass This table contains relative biomass indices of species that have been captured in every survey of the time series. The coefficient of variation and bootstrapped 95% confidence

These datasets contains information on fishing trips for deep7 bottomfish in the main Hawaiian Islands by contracted fishermen from March 2015 to November 2015 around Oahu, Maui, and the Big Island. Detailed information exists at the trip and station (fishing event) level. The trip specific data contains information on fisher and vessel, the port trip started in, start time and end time of trip, the dates fishing occurred over, and the species and size targeted. Information on depths fished, wave heights and wind speeds are also provided. The station specific data contains information on fishing set up including the number of hooks, species targeted, rigging type, bait used, and time fishing started and ended, and reason for ending. It also contained information on the environment including location, wave height, current, wind. The catch data contains vessel identification; station information; the date fishing took place; the time by reel that fishing started and ended; the species caught and their length and status; and the bait used.
